OPNSense DHCP Import

Overview

This simple script allows you to bulk import DHCP reservations to your OPNSense router.

It currently supports .csv files with a very specific format.

How-to

1. Generate a .csv file with the columns:

• macaddr
• ipaddr
• hostname
• description

2. Put your data into said CSV
3. Save the file into data/input_reservations.csv
4. Run opnsense-dhcp-import.py
5. Import generated XML backup data/output_dhcp_reservations.xml into OPNSense (specify DHCP only!)
6. Cross fingers, and test!

TODO

• Actually saving XML
• Other input formats
• JSON
• Other router backups?
• Testing
• OPNSense
• pfSense
• Maybe update OPNSense directly with API??!
